Former Barclays banker Roger Jenkins has been named Britain's richest high
street banker – with a fortune worth an estimated £150m.

Mr Jenkins, who left the bank in 2009 to set up his own advisory firm, beat former Barclay's colleague Bob Diamond, who is worth £102 million, according to the Sunday Times Rich List.

Mr Diamond succeeded John Varley as Barclays chief executive in 2010 on a salary of £1.35 million a year.

Ana Botin, head of Santander UK, was third among the bankers with a fortune estimated at £90 million, with Stuart Gulliver, HSBC chief executive, fourth at £54 million – tied with another Barclays executive Rich Ricci.

There is no lack of billionaires in the list, with hedge fund managers well represented: Sail Advisor's Robert Miller and Nat Rothschild, of Attara Capital, are both worth £1 billion followed by Alan Howard of Brevan Howard at £975 million.

The Sunday Times Rich List 2011 reveals that the 1,000 wealthiest people in the country are now worth a combined £395.8 billion, equivalent to more than a third of the national debt. With the number of billionaires having risen from 53 to 73, while nine people have seen their fortunes rise by £1 billion or more during the past 12 months alone.

Lakshmi Mittal, the steel tycoon, is again Britain’s richest man. However, the global financial crisis has seen his fortune fall by a fifth to £17 billion. Alisher Usmanov, the Russian mining magnate, has risen to become Britain’s second richest man after more than doubling his wealth to £12.4 billion.

Elsewhere, the Duke of Westminster has fallen outside the top three for the first time since 1999 with a fortune of £7 billion.
